TOTP / 2FA
Make or check two-factor one-time codes (TOTP).
Do things in TOTP / 2FA
Add a TOTP / 2FA step and choose an Operation. Choose the row to see the fields of each.
Later steps read a step’s output by its name: see Use data from earlier steps.

For developers
In the API, which calls apps pieces, TOTP / 2FA is pieceId: "totp" with actionId: "compute", set by operation. Get an app returns every field.
It computes from its inputs only (pure). See How versions and side effects work.
TOTP / 2FA › Generate / Verify TOTP
Generate a TOTP code or verify a user-supplied code against the current window.
Generate code
- Secret · Required
Base32-encoded shared secret (same value stored in your authenticator app).
- Digits · Optional
How many numbers the code has. Most apps use 6; pick 8 only if your setup requires it.
Options: 6 digits (standard), 8 digits (extended).
Default: 6 digits (standard).
- Algorithm · Optional
HMAC hashing algorithm. Leave on SHA1 unless your authenticator setup specifies otherwise: it must match whatever generated the secret.
Options: SHA1 (standard), SHA224, SHA256, SHA384, SHA512, SHA3-224, SHA3-256, SHA3-384, SHA3-512.
Default: SHA1 (standard).
- Period (seconds) · Optional
Time step in seconds (default 30 per RFC 6238).
Default: 30.
